Lantheus Faces Flurry of Investor Lawsuits Over Pylarify Disclosures as Lead‑Plaintiff Deadline Nears

Law firms are soliciting shareholders to seek lead‑plaintiff roles by November 10 in cases that have not been certified.

Overview

New Nov. 7 notices from DJS Law Group and The Schall Law Firm join earlier alerts from Bronstein, Bernstein Liebhard, Rosen, and Levi & Korsinsky about pending class actions.
The proposed class period covers purchases of Lantheus securities from February 26, 2025 through August 5, 2025.
Complaints allege Lantheus overstated Pylarify’s market leadership and downplayed competitive and pricing pressures that contributed to weakening sales in 2025.
Several filings cite violations of Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b‑5.
No class has been certified, investors are not represented unless they retain counsel, and participation is typically offered on a contingency‑fee basis.
